Just an update. We have the 4bbl setup complete on it. Painted the motor a dark gray color, put dual exhaust on it. Got 4 almost new tires put on it with hubcaps. Drove the car a little bit today. It has a stumble in the carb just off idle. Cant figure out why. We rebuilt the carb. It is avs/carter on it from a 66 chevelle. (I know its not mopar but its was on our shelf for some reason) The motor as far as we know is factory. Do I need to add zinc to the oil? It was suggested to me but no mention of how much or where to get it. Thanks Eric
